Beachborough & Brackley Triathlon 2026

Our annual triathlon — a highlight of the South Central Series — takes place in the stunning grounds of Stowe School, offering young athletes an inspiring and memorable race experience. The event returns on 14 June 2026, bringing together juniors from across the region for a day of exciting, well‑supported competition. Also back for another year are the very popular 4 X Relays on the same day.

With a friendly atmosphere, smooth organisation and a course perfectly suited to all levels, it’s a brilliant opportunity for both new and seasoned triathletes to test their skills and enjoy the buzz of race day.

The video on this page gives you a taster of what to expect on the day, but if you have any questions, please do get in touch.
